According to the 2012 National Survey on Drug Use and Health (NSDUH) report, Marijuana remains the most commonly used illicit drug, and it is also the third most popular recreational drug in the United States, behind alcohol and tobacco.
Latest estimates indicate that over 24 million people have used marijuana at some points in their lives, and 14 million use it regularly. However, misinformation about marijuana and its consequences abounds.
A team of scientists at the University of Florida has found that the theory of a “gateway drug” is not linked to marijuana, but to alcohol instead.
Namely, the Guttman scale showed that alcohol represented the gateway drug, leading to the use of tobacco, marijuana, and other illicit substances. Students who drank alcohol had an elevated risk of using both, licit and illicit drugs.
According to co-author Adam E. Barry, the study was conducted to flesh out some of the previous iterations. Apparently, while the latest form of the gateway theory is that it starts with cannabis and moves on finally to ‘harder drugs’, the truth is that it follows a progression from licit substances, specifically alcohol, and moves on to illicit substances.
Researchers from Yale also found that alcohol and cigarettes are more likely to precede opiate abuse than marijuana.
The study analyzed samples data collected from 14,577 high school seniors from 120 public and private schools in the United States. Researchers compared the substance abuse rates between non-drinkers and drinkers and discovered that seniors in high school who had consumed alcohol at least once in their lives were 13 times more likely to smoke cigarettes, 16 times more likely to use marijuana and other narcotics, and 13 times more likely to use cocaine.
Alcohol was also the most commonly used substance in the samples, and 72.2 percent of students admitted consuming alcohol at some point in their lifetime. On the other hand, 45 percent of students admitted smoking cigarettes, and 43.3 percent cited marijuana use.
The study concluded that alcohol should receive primary attention in school-based substance abuse prevention programming, as it can significantly affect the use of other substances.
Dr. Karen Van Gundy, an associate professor of sociology at the University of New Hampshire, agrees, claiming that whether marijuana smokers go on to use other illicit drugs depends more on social factors like stress and unemployment, not whether they smoked a joint in the eighth grade.
He claims that marijuana is not the most common and is rarely the first illicit drug used, as underage smoking and alcohol use typically precede marijuana use.
On the other hand, researchers have earlier found that cannabis can lower brain damage due to alcohol, and a chemical in it, cannabidiol, could be an effective remedy in the treatment of alcohol-induced neurodegeneration.
